So sorry, but I take back nothing…letting mis statements go unchallenged , lead others also un educated about the electrical field and in general electrical concepts that lay people are picking up from the local Home Depot need dispelling, you’re certainly not doing that.

Please explain how that neutral carries any current when the charging circuit uses 240 volts? I’m eagar to learn this exciting new Electrical concept. Include the NEC code section to save us verifying your claim.

You’re still wrong, the NEC even overrules Menlo Park, sorry once again. Guessing you should stay in your lane on what you really know versus, what you think you know…40+ years NECA and IBEW member.

I think you should put your money where your mouth is and start an Electrical contracting business…you seemingly could really clean up in LA, if you could only suspend that pesky NEC and avoid local Electrical inspection there, that is.

Also if reducing fully the overall costs, note the neutral and ground wire certainly don’t have to be #4, ask your electrician, he’ll be able to tell you what size he’ll be installing…just sayin.

Then if something goes wrong, will you step up and tell your insurance company that you did the install, removing their liability in insuring your home? (I already know your answer) As a contractor along with all the municipal licenses I carried, the amount of continuing education, I had to...

Did a quick calc on my voltage drop calculator, length shows up at 200 feet with that drop and #12 wire, but remember it’s the total length of both the hot conductor going out and the neutral coming back to the source for the calculation… Extra resistance can occur in splices also, just...

Plugged in, and switched off until needed for charging, via a two pole industrial switch.

@Gatorpharm I used to work alongside a “builder” (General contractor) he didn’t know *sugar* (but thought he did) about electrical installs, just sayin...Retired IBEW/NECA Electrical contractor. Agree with all the recommendations to get a real Electrician to check out your problem...

No this was in my own home, and was installed by myself. Nothing was loose, and no insulation under the clamping screw. The problem was the proximity of grounding yolk, that’s pointed out in by the picture with the pen and the new design of that’s same manufacturer’s heavy duty receptacle. The...

Here’s a few shots of what a premium receptacle does when it faults (not the HD $.79 variety, keep that in mind when you’re passing 16 amp’s through your car charging on successive nights...Again keep that fire insurance paid up... PS there was only a few amps load on this, prior to when it...

I’m astounded by the assumption it’s only feeding one receptacle. Unless it’s in conduit that you can easily trace, it would remain just that, an assumption. Then at some time in the future when something gets plugged into that newly minted 240 volt circuit somewhere else, get ready for the...

@KenC, If you couldn’t ascertain which “leg” each 120 volt circuit was on prior to envisioning their combination, you might not end up with 240 volts at all. That said, you’ve also got regulatory hurdles to overcome “NEC” and local electric inspection to deal with, but not totally impossible...

Any 6-50 installed in a single gang box I would say is not following the box/wire spacing off the NEC...

Just my observation, but curious why no one seems remotely concerned with applying the sizing requirements of single gang boxes for these fly by night “electrician” installs...? This is a target rich environment for how not to install charging receptacles. “YouTube” and others who’ve possibly...

Get plenty-o-fire insurance prior to your quest...

I just took a look at the California contractors board... the contractor you’ve chosen didn’t show up as licensed... That may be the reason of a lower price.

I see how my statement was misinterpreted, but by no means does it make this statement by yourself true...There would be only one amp flowing in your imaginary flashlight circuit... My statement was just for those not too informed as to the total wattage draw they would experience with that...

I certainly didn’t mention the main breaker tripping at 80% of it’s rating...the main breaker may not trip at 130% or more of it’s rating, it’s condition, how many times it’s been exercised will influence it’s trip point...imho.

Please enlighten me...?

Noted, but far fewer people are in your situation, as the original op was asking for information on one 40 amp charging circuit. If this DCC-10 was installed all it may prevent is the main breaker tripping, but that’s dependent on the condition of the main breaker...

I for one am glad there’s fewer 110/220 references...

Wow, that’s quiet the pricy addition for a job that basically is done for nothing by the existing circuit breaker feeding any charging circuit. As that said charging circuit will already have been limited to 80% as it’s considered a continuous load, one that runs for over three hours. The...

How and why allowed this to happen? If this “plug” was that loose, your lucky the whole place didn’t burn down around you...Have someone who is a real “Electrician” check out and remedy your situation. Next get trained on how to adequately insert the plug...all the way in.

I’m looking at the difference in reflection, in the two connectors in the first picture...the first containing the feed looks to be dull and may be pvc, and wouldn’t be able to supply any grounding. It also appears to be connected via a concentric knock out which is not sufficient to supply...

Just thinking if it was #8 thhn in conduit (not romex) that’s allowable to carry the 50 amps, but the breaker definite too small.

Do that same exercise for your air conditioner...betting that takes the cake...

If only more electricians had access or had in their possession an Ideal circuit analyzer 61-165 or the current model, it easily lets you know the condition of any branch circuit, and it’s potential voltage drop at both 16 and 20 amps of load...plus circuit wire resistance all without unscrewing...

Your Tesla charger wants to keep you/occupants safe...to accomplish that it wants to see a good grounding path. It’s not the electrical system, it’s the criteria Tesla is demanding... PS your garage door, and whatever lighting are fractional currents compared to load your car will add to the...

You mention trenching to get larger wiring (not higher bandwidth) installed from the house supply?, that may be the problem you’re experiencing and it may take replacement of the existing wiring to remedy the problem as the condition of those underground wires may be at fault... As to what...

Voltage drop is a product of any amperage drawn, and length of a particular wire gauge (size) as distance and amperage goes up, so does voltage drop. Your extension cord adds to the overall voltage drop, the condition and age of that cord has some bearing also (old, and with some strands...

Call your agent, let him know you’ve got a broken glass claim... that’s all it takes.

https://www.gordonelectricsupply.com/p/Hubbell-Rr430F-30A-125-250V-Sb-Recpt/6157688 Here’s the Hubble 14/30 receptacle, I installed in a similar situation, uses the same 10/3 with ground romex cable... just adds a neutral JIC it’s ever needed.

I’d be curious enough to check what type of existing wring is installed for your dryer plug, (possibly aluminum which isn’t optimum), but think a new run done in the appropriate copper conductors, complete with plug in the garage should be what you eventually chose. That 240/30 amp circuit will...

My take is we have a forum with a cross section of participants, where many have little to no electrical background. The expectation is that most by participating in this and some similar forums will gain some useful information, but never fully understand what’s going on, and more importantly...

Lawyers are going to luv it... Glad I’m not living in any of those trial by fire area’s... Don’t get me wrong, love the car and agree 100% with @mark95476 above on feature used but also glad I didn’t opt for the FSD...

Unlike the comments attesting that they’ve assessed that this is a sub panel, not everyone who posts actually knows *sugar* about what they’re about to post. That said with the help of a licensed electrician/contractor I’m sure they could come up with a few ways to get you at least a 240 volt...

So just curious how the forum feels, especially those Tesla owners who've already purchased the full self driving feature with the new revelation from Tesla to the California DMV..? Tesla Tells California DMV that FSD Is Not Capable of Autonomous Driving

A good understanding of the national Electrical code from anytime in the last ten years (NEC) would benefit many on this subject...

Curious about what background, certifications, professional training, or completed apprenticeships you’re basing your “from what I’m understanding statement” with...? Reason I’m asking is, any Electrical work requires education, training and the application of those learned premises, and...

Just received a complete set of the weathertech mats front, second row and cargo trunk. Trunk mat is great, nice fit, but am not liking the mats. We're in Northern California and though it does rain, it's not epic. Thinking of returning them and ordering the replacement carpet mats that...

I think we have something similar, it's method of attachment is through Velcro which hooks into the carpet, leaving it's affects when said organizer is removed or relocated.

Musing of the days when we had cheap gas $.19/gallon, driving a ‘72 VW Beetle, never dreaming a Tesla was ever in my future... All that the future was supposed to bring, failed on many accounts but did deliver EV’s finally... Who could’ve known...?

I misspoke, wasn’t a quote, just a ROM for that glass versus the top glass...

How about golf ball...That's it in the center near the end of the heating grid, right? Agree, just go with your insurance, I think I was quoted $700 or so for the back glass, even though it's smaller than the top glass which just set my insurance back $1,200, mine was from a rock on the highway.

Just to set the record straight, from a L14-30R receptacle (4 wire 30 amp 240 volt) on a thirty amp circuit, you can expect 22/miles/per hour of charge, not 14.. (charging at 24 amps).

2015-2020 GM Guide 13526043 | TascaParts.com, just found the same thing, but don’t know if it will work... Maybe @mwfriederichs can add his experience?

My wife 5’ has that same problem, maybe try to get one of those sheepskin belt covers...

After re-reading the OP’s complaint, he’s having problems at two separate locations, using the same mobile charger. Doesn’t a supercharger bypass the car’s internal inverter? That must be where the problem is residing (in the car), if it isn’t the mobile charger... I can’t see the same...
